Abstract
An improved coupling (10) to be embedded in concrete (101) is described. The coupling includes multiple concentric rings (11c) on an outside wall (11a) of a tube (11) which aid in preventing leakage along the outside wall and which help in providing fire retardancy. The coupling includes a step form (14) having a regular diameter which aids in positioning the coupling using a template (105).
Description
(1.) Field of the Invention
The present invention relates to an improved coupling (10) adapted to be embedded in concrete (101). In particular, the present invention relates to a coupling having regularly spaced concentric rings (11c) on the outside (11b) of the coupling which provide a water tight seal with the concrete and which provide a means for adjusting the height of the coupling prior to installation by cutting to conform with the concrete pour upper surface (101a or 101b) to provide a flush fit.
(2) Prior Art
The prior art in my U.S. Pat. No. 4,261,598 describes an improved coupling. This coupling works very well but allows water to seep between the interface of the outside wall 13 of the tube 11 and the concrete 300. Further each pour of cement 300 requires a different height extension 100 with or without water closet flange 400. With my earlier coupling, solvent welding of the tube 11 pipe to the coupling was necessary for extension which required additional effort and resulted in a joint which might leak. Finally, my earlier coupling provided no protection from melting in case of fire.
It is therefore an object of the present invention to provide an improved coupling (10) which reduces the possibility of leakage between the concrete and coupling interface. Further it is an object of the present invention to provide a coupling (10) which reduces melting due to fire. Further still it is an object of the present invention to provide a coupling (10) which is readily adjustable to different heights by cutting for different cement pour heights (101a or 101b). These and other objects will become increasingly apparent by reference to the following description and to the drawing.
FIG. 1 is a front view of a coupling (10) showing concentric rings (11c) which are at a predetermined height from the base (12a) of a circular flange (12).
FIG. 2 is a front cross-sectional view of the coupling (10) of FIG. 1 and including in addition a removable cap (15) used during pouring of the cement and showing plastic pipe (102) in dotted lines which is installed after pouring
FIG. 3 is a front cross-sectional view of the coupling (10) of FIG. 2 wherein a small diameter pipe (200) is held in place by retainers (300) and wherein a fire retardant packing (305) is provided inside the coupling.
The present invention relates to a coupling (10) having spaced apart parallel cylindrical inside and outside walls which coupling is adapted to be embedded in a concrete floor (101) for supporting pipe (102, 200) and to be at least temporarily supported by a form (100) for pouring the concrete floor which comprises:
(a) a tube 11 having an inside cylindrical wall (11a) defining a cylindrical longitudinal axis (A--A), an outside wall (11b) and opposing ends between the walls;
(b) an inside annular rim (11f) between the ends and around the inside wall of the tube with two spaced apart parallel shoulders (11g and 11h) which are perpendicular to the axis of the tube and with an annular face (11f) between the shoulders which is parallel to the axis of the tube;
(c) attachment means (12) at one end of the tube for securing the coupling to the form using connection means; and
(d) a series of equally spaced apart concentric rings (11c) on the outside wall of the tube, wherein the rings are at predetermined heights relative to the attachment means.
Referring to FIGS. 1 and 2, the improved pipe coupling 10 of the present invention is shown. The coupling 10 is preferably an integral unit made of injection molded plastic (PVC) and includes a cylindrically shaped tube 11 having a cylindrical inside wall 11a defining a longitudinal axis A--A and a parallel cylindrical outside wall 11b and with a flange 12 at one end of the tube 11. The outside wall 11b has a series of parallel concentric rings 11c positioned such that the lower surface 11d is exactly an even number of inches (or centimeters) from the lower surface 12a of flange 12 and the dimension is preferably marked on the outside wall 11b of the tube 11 as shown in FIG. 1 for reasons which will become apparent. The rings 11c have lower surfaces 11d and upper surfaces 11e which are perpendicular to the longitudinal axis A--A of the tube 11.
The flange 12 includes holes 13 for nails or screws 102 which hold the coupling 10 in position on a pouring form 100 (shown in dotted lines in FIGS. 2 and 3). The lower surface 12a of the flange 12 is secured to the pouring form 100 using the nails or screws 102 as shown in FIG. 3 or by gluing (not shown). Adjacent to the upper surface 12a of flange 12 is a step form 14, concentric with and spaced from the lower most pour ring 11c, which has a radius which is the size of a standard size hole cutter so that the step form 14 fits in closely spaced relationship to a hole 104 in template 105 (as shown in dotted lines). The template 105 is used to position multiple couplings 10 so that piping (not shown) can be prefabricated for installation between couplings on the same level.
The inside wall 11a of the tube 11 includes an inner concentric annular rim 11f which is adapted to receive plastic pipes or the like which abut on spaced apart upper and lower shoulder surfaces 11g and 11h respectively, both of which are perpendicular to the longitudinal axis A--A of the tube 11.
The face 11i of the inner annular rim 11f is parallel to the longitudinal axis A--A and preferably projects towards the axis to produce a height (length of shoulders 11g and 11h) which is about equal to the wall thickness of a standard pipe 102 or 103 (as shown in dotted lines in FIG. 2). The inner wall 11a of tube 11 includes a chamfered portion 11j adjacent to the flange 12.
With the coupling 10 at a selected height, a cover 15 (FIG. 2) is placed over the outside surface 11b of the wall 11 at the end of tube 11 opposite the flange 12. This prevents cement from entering the inside of the coupling 10 during pouring and allows a cement finisher to pass over the coupling 10 at upper surface 101a or 101b of the concrete 101.
In use, a removable wooden form 100 is positioned for pouring of a concrete floor 101. The coupling 10 with the cap 15 is mounted on the form 100 and secured by nails 102 (FIG. 3), gluing or the like such that the surface 12a of flange 12 is against the form 100. The position of the coupling 10 can be set by template 105. The cement 101 is poured and allowed to set. The cap 15 which is usually a bright color for easy detection is then removed after the cement is set. The pipe 102 and 103 can then be mounted against the annular rim 11f at either end of the coupling 10 and inner wall 11a in a press fit and solvent welded. The chamfer 11j adjacent the flange 12 aids in starting the pipe in the tube 11 opening 16.
The coupling 10 of the present invention provides ease of installation during pouring of the cement 101. The concentric pour rings 11c and provide a good water seal between the coupling 10 and the cement 101. The rings 11c also provide a heat sink affect because of the concrete 101 which retards melting of the coupling 10 during a fire. Because of the height markings on the coupling 10, it is a simple matter for a wholesaler or other distributor to cut the couplings adjacent the underside 11d of a ring 11c to provide a coupling height corresponding to the concrete 101 pour height. The coupling 10 greatly reduces the cost and difficulty of providing plastic piping 102 or 103 between floors in a building. Further the coupling 10 can be used for other purposes such as mounting metal pipe as shown in FIG. 3 and toilet flange mounting as shown in U.S. Pat. No. 4,261,598.
FIG. 3 shows the coupling 10 mounted on a permanently placed pouring form 106 with opening 104 with a metal pipe 200 installed using elastic (rubber) retainers 300 at opposite ends of the coupling 10. The retainer 300 includes a top 301 which serves to aid in driving the retainer 300 in place with a hammer. Outer lip 303 aids in sealing to the inner wall 11a of tube 11 and inner lips 304 seal to the outer wall 200a of pipe 200. The retainer 300 is preferably split (not shown) in a plane parallel to the longitudinal axis A--A in order to provide a means of placing the retainer 300 over the installed pipe 200. Once installed the compression of the retainer 300 by the pipe 200 and wall 11a compresses the slit to provide a tight fluid seal.
As can be seen from FIG. 3 the retainer 300 with coupling 10 provides an easy and permanent means for holding pipe 200 in place. The retainer 300 can be sold with the couplings 10 as a kit for installation of metal pipe 200. The space 16 between the pipe 200 and inside wall 11a can be with packed with a ceramic fiber filter 305 or the like to provide fire retardancy. The filler 305 can be packed into coupling 10 from the flange 12 end as shown in FIG. 3 or from the opposite end above the coupling 10 with the retainer 300 in place at the flange 12 end. Generally it is easier to insert the filler 305 from above rather than below as shown in FIG. 3.
The preferred form of coupling 10 of the present invention is shown in FIGS. 1 to 3. Numerous variations will occur to those skilled in the art and are intended to be included within the scope of the present invention.
